Valuable dyestuff formulations for dyeing polyester fibres are obtained without expensive finishing techniques by simple mixing of emulsifiers with dyestuffs of the formula <IMAGE> wherein A=alkylene, B and D=a direct bond or a bridge member, V and Q=hydrogen, alkyl, alkenyl, cycloalkyl, aralkyl, aryl or acyl, X and Y=a non-ionic substituent, m and n=0 to 3 and p and r=0 to 10, with the proviso that p represents 3-10 if r=0 or 1 and D=a direct bond. The dyeing formulations are present in the liquid or dissolved form under the dyeing conditions. The use of dispersing agents, protective colloids, levelling agents and carriers is thus superfluous.
